That is funny you should mention your audio as I searched all over your site trying to find the who, what and where as it really adds a nice touch to viewing the slide show. I really enjoy your work, I think the variety, composition and lighting is what I am drawn to. The addition of the human element also opens up your work to a wider audience as now these are not just train images but captures of what could be a much earlier time. I think this is what many us want to experience in our rail fanning/ photo shoots. Perhaps you can expand on this thought to help the operators and organizers address this need.

P.S. I would love to see you partner with either tourist RRs or maybe the larger TRA to have a traveling interactive exhibit/ slide show in malls etc. to attract the public to support and visit tourist operations and museums.
